Harley Benton Rockplug Classic Rock

Simple and good, depending on your headphones

Super simple device, reasonable sound for practicing alone. There is not a lot of tonal variety, and the quality seems to depend heavily on your headphones. But it’s cheap, super portable and sounds good enough.

Noisy

A nice device with a mini USB charging port, decent battery, but all the advantages are negated by one big disadvantage: The device emits high-frequency noise, even if no instrument is connected. I tried different headphones and speakers, it is possible to reduce the volume of the noise signal, but it’s impossible to get rid of it completely.

Good features, lacking tone

Pros: Built-in battery which is pretty powerful Good controls Cons: Just one - weak and fuzzy tone Tried multiple headphones and instruments with the same results. I like classic rock but this is not really that tone with neither single coils nor humbuckers.

plug has to be forced into strat input

sounds pretty good, the price is right, but the housing of the plug doesn't fit well into a strat input on the top of the guitar

Great value for the price.

It doesn't have fancy features and million buttons. Set your overdrive and tone, plug the headphones and it's good to go. Simple product and it does the job. Sound is decent, both played clean and played heavy with distortion. Controls are smooth, battery life surprisingly long. Maybe build quality feels a bit flimsy, but again, it's 15 euros. Comparable products from big brands start at 3x the price.

Annoying ringing sound

It has a very annoying ringing sound that never goes away, and the tone is basically either 0 or 100, it's very difficult to manage it, but it's a fun toy to play around with an costs nothing

Simple great plug & play

This is a go to cheap as chips way of practicing any guitar (or sounds great with bass) if you are too lazy to reach for the amplifier

pretty decent headphone amp

It is cheap and surprisingly good for its price! if you are on a budget this will definitely worth the money. it has some weird distortion sounds but overall it is great, I can't say anything about it because it is cheap

Holiday Amp

Use this as a travel amp when on my hols. Does the job perfectly.

Very nice plug

Very nice plug for this money. Of course it doesn't have a lot of effects, only overdrive. And it reminds me of fuzz pedal.

Also its humming a little bit. But nothing critical.
